International Comfort Products C8DNL125L20A1 Control Board
The control board is created to control everything including the gas valve, the igniter, all the sensors and the blower all together. Your furnace or AC will not operate whatsoever unless this board is correctly installed. You should always be careful while selecting a replacement because of the many variances of brand and air handler types. The control board picked will need to pair with the part number from both the brand and model of the system you have installed.
